Concrete Mixing

But if there is too much water in the concrete mixture, the chemicals and granules are thinned out and the structural integrity of the resulting concrete is compromised. The rainy season can mess up with the balance of water and the mixture. The moisture-rich air and direct exposure to rain can cause the mixture to have more water than what is ...

Temperature and relative humidity: What they mean for you and

Concrete needs to remain moist in order for it to cure. Generally the internal relative humidity needs to be above 80% to 85% relative humidity for hydration to take place. Wetting the surface of bare concrete creates a barrier of water that prevents the moisture from inside the concrete from being drawn out when the surface moisture evaporates.
